  Ask Dr ? Jeffers

This month Dr. Jeffers is answering questions about the human brain and how it works.

Dear Dr. Jeffers,

One of my colleagues, Felix Moeller, told me that scientists are learning to use computer to ‘read minds’. Is there any truth to this story/

Jane Leon, New York, USA

Dear Ms. Leon,

Well, a lot of research is being conducted in this area, but so far, the brain scanning equipment and corresponding computer programs haven’t been able to actually read thoughts. In one experiment, test subjects(受试者)were connected to scanning equipment and shown two numbers on a screen. They were then asked to choose between adding or subtracting(减)the two numbers. Using this method, researchers were able to follow brain processes and make the correct assumptions(假设)70 percent of the time. It’s not quite mind reading, but it’s certainly a first step.

—Dr. J.

Dear Dr. Jeffers,

My three-year-old son loves it when I dig my fingers into his sides and tickle (胳肢)him until he laughs uncontrollably. The other day I noticed him trying to tickle himself but he couldn’t do it. Why not?

Glenn Lewis, Vancouver, Canada

Dear Mr. Lewis,

It’s because of how the brain works. The brain is trained to know what to pay attention to and what to ignore. It causes us to ignore physical feelings we expect to happen, but it causes a mild panic reaction when there is an unexpected feeling. For example, you don’t notice how your shoulder feels while you’re walking down the street. But if someone comes up behind you and touches you lightly on the shoulder, you may jump in fear. It’s that unexpected part that causes the tickle reaction.

Dr. J.

My mind seems always to return to the day when I met Carl. The city bus stopped at a corner to pick up the daily commuters (someone who travels regularly to and from work), a group in which I was included. Boarding the bus, I looked for a place to sit. At last, I found a place near the back.

The man in the seat next to the one I was going for was an older man in a grey suit, well-worn dress shoes, and a black hat like I always pictured reporters wearing, but without the little press card. Seated, I began to read the book I had been carrying, which was Jack Kerouac’s On the Road. The man in the seat next to me introduced himself by asking if I had read any other book like the one I was holding. When I told him I had, he seemed to become interested, and so did I. He introduced himself as Carl and asked if I liked jazz, and I told him that I didn’t really listen to it, and that I liked rock and roll. Waiting for Carl to tell me that I should listen to real music, I was shocked when he just smiled and nodded. He said, "You remind me of myself when I was your age. I remember how my parents hated jazz and how they couldn’t see how I could listen to that awful noise. I bet your parents say the same thing, don’t they?" Now it was my turn to smile, amused with how right he was.

As the bus carried us from one side of the city to the other, Carl and I talked about a lot of different things. The more we talked, the more amazed I became at how much the two of us really had in common, despite the age difference. I haven’t seen him since we parted, but the thought of our connection that day rarely leaves my mind.

       Carl really made me think about how much we can learn from each other if we just break through the blocks between us we’ve got. I mean, I would have never thought before that day that I could have anything in common with someone so much older than I. But Carl taught me that no matter what we are, we are all just people, and that we should make an extra effort to try and get to know our neighbors and people we see every day, regardless of age, race, religion, sex, or anything else. If we all take the time to attempt to understand each other, I think that the world would be a much better place that we could share together, as humans.

your eyes, Man," the Cat said. The Man gave him a questioning look, but did as he was told.

for hours with it. '"Now take each end of the string in one hand," the Cat ordered. The Man did so.

"The end in your left hand is my birth and the end in your right hand is my   45 . Now bring the two ends together," the Cat said. The Man obeyed.

"You have made a continuous  46   ," said the cat. "Does any point along the string appear to be different, worse or better than any other part of the string?" The Man inspected the string and then   47  his head " no".

The Man shut his eyes hard as the tears poured down his face. He saw the Cat on the  48   , then in his bed, then lying across his important papers. He saw him on the pillow next to his head, saw his bright gold eyes and darkest brown on his nose and ears. He opened his eyes and  49  his tears looked over at the circle of string he still held in his hand.         

One day, not long after, there was a new Cat on his lap. She was lovely and white…very different from his earlier   50  Cat and very much the same.
